Solve the system of equations - 4x + 8y = 40 and -2x + y = -10 by combining
the equations.

Explain how you do each step what term makes it inconsistent y=2x - 4 ?

Mozart lenses inc. recently introduced seelites, a thinner lens for eyelasses. of a sample of 800 eyeglass wearers, 246 said they would purchases their next pair of eyeglasses with the new lenses. lenses inc. estimates that the number of people who purchase eyeglasses in a year is 1,700,000. most eyeglasses wearer buy one new pair of eyeglasses a year. what is the annual sales potential for the new lenses.

Complete the solution of the equation. find the value of y when x equals to 6 4x+y=20
